Embodiment 1

[0027] Follow the steps below to make a styrofoam trim panel:

[0028] (1) Wash the pumpkin skin and air-dry it for 5 days, cut it into small pieces of 5cm×1cm, put it into 5 times the weight of distilled water, take it out after soaking for 24 hours, and transfer it to a continuous steam blasting machine for blasting treatment to obtain the crude pumpkin skin. Fiber, the steam pressure is 2MPa, and the holding time is 150s;

[0029] (2) Add the pumpkin skin crude fiber obtained in step (1) into a sulfuric acid solution with a mass concentration of 20%, the mass ratio of the pumpkin skin crude fiber to the sulfuric acid solution is 1:12, heat to 60°C and stir for 1.5 hours, take out Finally, wash with deionized water until neutral, beat with an iron rod, turn over once every 5 minutes, repeat 5 times, soak and wash with distilled water for 5 minutes, and obtain pumpkin skin fibers after drying;

[0030] (3) the pumpkin peel fiber that step (2) obtains is added in the sodium h...

Abstract

The invention provides a polystyrene foam decorative sheet and a manufacturing method thereof. The manufacturing method roughly includes the following steps that (1) pumpkin peels are cleaned, subjected to air drying, cut to be small and soaked to be subjected to steam explosion, and pumpkin-peel crude fibers are prepared; (2) the pumpkin-peel crude fibers are treated with sulfuric acid and then beat with an iron bar, and pumpkin peel fibers are obtained; (3) the pumpkin peel fibers are treated with a sodium hydroxide solution to obtain alkali-treatment pumpkin peel fibers; (4) the alkali-treatment pumpkin peel fibers, acetic anhydride, glacial acetic acid and ammonum persulfate are reacted, and modified pumpkin peel fibers are obtained; (5) polystyrene is prepared into particle materials, the particle materials and other components are stirred into mixed materials, a foaming agent is injected, foaming, cooling, extruding, cooling and shaping are carried out, and the polystyrene foam decorative sheet is obtained. The polystyrene foam decorative sheet manufactured with the method has the high toughness, and is prone to degradation and quite environmentally friendly.

Description

technical field [0001] The invention relates to a decorative board, in particular to a polystyrene foam decorative board and a manufacturing method thereof. Background technique [0002] Polystyrene refers to a polymer synthesized by free radical polycondensation of styrene monomers. The English name is Polystyrene, referred to as PS. Polystyrene (PS) includes ordinary polystyrene (GPPS), expandable polystyrene ( EPS), High Impact Polystyrene (HIPS) and Syndiotactic Polystyrene (SPS). Ordinary polystyrene resin is an amorphous polymer. The side groups of polystyrene macromolecular chains are benzene rings, and the random arrangement of bulky side groups is benzene rings, which determines the physical and chemical properties of polystyrene, such as high transparency. , high rigidity, high glass transition temperature, brittle and so on. Expandable polystyrene is made by impregnating low-boiling point physical blowing agent in ordinary polystyrene, and it is heated and foame...
